↵a Data, including those on ESBL detection, are from the participating hospitals' antimicrobial susceptibility reports. The susceptibility breakpoints (μg/ml) for all isolates are as follows: ≤8, cefepime; ≤4, imipenem; ≤16, amikacin; ≤1, ciprofloxacin. The susceptibility breakpoints of ceftriaxone are ≤1 μg/ml for Enterobacteriaceae and ≤8 μg/ml for P. aeruginosa and A. baumannii. The susceptibility breakpoints (μg/ml) of ceftriaxone are ≤1 and ≤8 for the Enterobacteriaceae P. aeruginosa and A. baumannii. The susceptibility breakpoints (μg/ml) of piperacillin-tazobactam are ≤64 and 4 for P. aeruginosa and ≤16 and 4 for A. baumannii.
